More is known about shallow water coral reefs in tropical zones than deep-water reefs discovered recently, however much research into these unique ecosystems is being conducted. Tropical coral reefs are biotic reefs formed in tropical waters by live organisms such as calcareous algae (including red algae) and corals. In contrast, abiotic reefs are formed by the deposit of sand and other materials in shallow water.
Widespread bleaching and mortality of reef-building corals occurred in the tropical eastern pacific region during the severe and prolonged el niño-southern oscillation (enso) event of 1982-83.
